[0031] Suitable water-soluble non-soap, anionic surfactants used in theinstant compositions include those surface-active or detergent compoundswhich contain an organic hydrophobic group containing generally 8 to 26carbon atoms and preferably 10 to 18 carbon atoms in their molecularstructure and at least one water-solubilizing group selected from thegroup of sulfonate, sulfate and carboxylate so as to form awater-soluble detergent. Usually, the hydrophobic group will include orcomprise a C⁸-C²² alkyl, alkyl or acyl group. Such surfactants areemployed in the form of water-soluble salts and the salt-forming cationusually is selected from the group consisting of sodium, potassium,ammonium, magnesium and mono-, di- or tri-C₂-C₃ alkanolammonium, withthe sodium, magnesium and ammonium cations again being preferred.

[0032] Examples of suitable sulfonated anionic surfactants are the wellknown higher alkyl mononuclear aromatic sulfonates such as the higheralkyl benzene sulfonates containing from 10 to 16 carbon atoms in thehigher alkyl group in a straight or branched chain, C₈-C₁₅ alkyl toluenesulfonates and C₈-C₁₅ alkyl phenol sulfonates.

[0033] A preferred sulfonate is linear alkyl benzene sulfonate having ahigh content of 3—(or higher) phenyl isomers and a correspondingly lowcontent (well below 50%) of 2—(or lower) phenyl isomers, that is,wherein the benzene ring is preferably attached in large part at the 3or higher (for example, 4, 5, 6 or 7) position of the alkyl group andthe content of the isomers in which the benzene ring is attached in the2 or 1 position is correspondingly low.

[0034] Other suitable anionic surfactants are the olefin sulfonates,including long-chain alkene sulfonates, long-chain hydroxyalkanesulfonates or mixtures of alkene sulfonates and hydroxyalkanesulfonates. These olefin sulfonate detergents may be prepared in a knownmanner by the reaction of sulfur trioxide (SO₃) with long-chain olefinscontaining 8 to 25, preferably 12 to 21 carbon atoms and having theformula RCH═CHR₁ where R is a higher alkyl group of 6 to 23 carbons andR₁ is an alkyl group of 1 to 17 carbons or hydrogen to form a mixture ofsultones and alkene sulfonic acids which is then treated to convert thesultones to sulfonates. Preferred olefin sulfonates contain from 14 to16 carbon atoms in the R alkyl group and are obtained by sulfonating ana-olefin.

[0035] Other examples of suitable anionic sulfonate surfactants are theparaffin sulfonates containing 10 to 20, preferably 13 to 17, carbonatoms. Primary paraffin sulfonates are made by reacting long-chain alphaolefins and bisulfites and paraffin sulfonates having the sulfonategroup distributed along the paraffin chain are shown in U.S. Pat. Nos.2,503,280; 2,507,088; 3,260,744; 3,372,188; and German Patent 735,096.

[0036] Examples of satisfactory anionic sulfate surfactants are theC₈-C₁₈ alkyl sulfate salts the ethoxylated C₈-C₁₈ alkyl ether sulfatesalts having the formula R(OC₂H₄)_(n) OSO₃M wherein n is 1 to 12,preferably 1 to 5, and M is a metal cation selected from the groupconsisting of sodium, potassium, ammonium, magnesium and mono-, di- andtriethanol ammonium ions. The alkyl sulfates may be obtained bysulfating the alcohols obtained by reducing glycerides of coconut oil ortallow or mixtures thereof and neutralizing the resultant product.

[0037] On the other hand, the ethoxylated alkyl ether sulfates areobtained by sulfating the condensation product of ethylene oxide with aC₈-C₁₈ alkanol and neutralizing the resultant product. The alkylsulfates may be obtained by sulfating the alcohols obtained by reducingglycerides of coconut oil or tallow or mixtures thereof and neutralizingthe resultant product. The ethoxylated alkyl ether sulfates differ fromone another in the number of moles of ethylene oxide reacted with onemole of alkanol. Preferred alkyl sulfates and preferred ethoxylatedalkyl ether sulfates contain 10 to 16 carbon atoms in the alkyl group.

[0038] The ethoxylated C₈-C₁₂ alkylphenyl ether sulfates containing from2 to 6 moles of ethylene oxide in the molecule also are suitable for usein the inventive compositions. These surfactants can be prepared byreacting an alkyl phenol with 2 to 6 moles of ethylene oxide andsulfating and neutralizing the resultant ethoxylated alkylphenol.

[0039] Other suitable anionic surfactants are the C₉-C₁₅ alkyl etherpolyethenoxyl carboxylates having the structural formula R(OC₂H₄)_(n)OXCOOH wherein n is a number from 4 to 12, preferably 5 to 10 and X isselected from the group consisting of CH₂, (C(O)R₁ and

[0040] wherein R₁ is a C₁-C₃ alkylene group. Preferred compounds includeC₉-C₁₁ alkyl ether polyethenoxy (7-9) C(O) CH₂CH₂COOH, C₁₃-C₁₅ alkylether polyethenoxy (7-9)

[0041] and C₁₀-C₁₂ alkyl ether polyethenoxy (5-7) CH₂COOH. Thesecompounds may be prepared by condensing ethylene oxide with appropriatealkanol and reacting this reaction product with chloracetic acid to makethe ether carboxylic acids as shown in U.S. Pat. No. 3,741,911 or withsuccinic anhydride or phthalic anhydride. Obviously, these anionicsurfactants will be present either in acid form or salt form dependingupon the pH of the final composition, with salt forming cation being thesame as for the other anionic surfactants.

[0042] The amine oxide semi-polar nonionic surfactants comprisecompounds and mixtures of compounds having the formula

[0043] wherein R₁ is an alkyl, 2-hydroxyalkyl, 3-hydroxyalkyl, or3-alkoxy-2-hydroxypropyl radical in which the alkyl and alkoxy,respectively, contain from 8 to 18 carbon atoms, R₂ and R₃ are eachmethyl, ethyl, propyl, isopropyl, 2-hydroxyethyl, 2-hydroxypropyl, or3-hydroxypropyl, and n is from 0 to 10. Particularly preferred are amineoxides of the formula:

[0044] wherein R₁ is a C₁₂₋₁₆ alkyl and R₂ and R₃ are methyl or ethyl.The above ethylene oxide condensates, amides, and amine oxides are morefully described in U.S. Pat. No. 4,316,824 which is hereby incorporatedherein by reference.

[0045] The alkyl polysaccharides surfactants, which are used inconjunction with the anionic surfactants have a hydrophobic groupcontaining from about 8 to about 20 carbon atoms, preferably from about10 to about 16 carbon atoms, most preferably from about 12 to about 14carbon atoms, and polysaccharide hydrophilic group containing from about1.5 to about 10, preferably from about 1.5 to about 4, most preferablyfrom about 1.6 to about 2.7 saccharide units (e.g., galactoside,glucoside, fructoside, glucosyl, fructosyl; and/or galactosyl units).Mixtures of saccharide moieties may be used in the alkyl polysaccharidesurfactants. The number x indicates the number of saccharide units in aparticular alkyl polysaccharide surfactant. For a particular alkylpolysaccharide molecule x can only assume integral values. In anyphysical sample of alkyl polysaccharide surfactants there will be ingeneral molecules having different x values. The physical sample can becharacterized by the average value of x and this average value canassume non-integral values. In this specification the values of x are tobe understood to be average values. The hydrophobic group (R) can beattached at the 2-, 3-, or 4-positions rather than at the 1-position,(thus giving e.g. a glucosyl or galactosyl as opposed to a glucoside orgalactoside). However, attachment through the 1-position, i.e.,glucosides, galactoside, fructosides, etc., is preferred. In thepreferred product the additional saccharide units are predominatelyattached to the previous saccharide unit's 2-position. Attachmentthrough the 3-, 4-, and 6-positions can also occur. Optionally and lessdesirably there can be a polyalkoxide chain joining the hydrophobicmoiety (R) and the polysaccharide chain. The preferred alkoxide moietyis ethoxide.

[0046] Typical hydrophobic groups include alkyl groups, either saturatedor unsaturated, branched or unbranched containing from about 8 to about20, preferably from about 10 to about 18 carbon atoms. Preferably, thealkyl group is a straight chain saturated alkyl group. The alkyl groupcan contain up to 3 hydroxy groups and/or the polyalkoxide chain cancontain up to about 30, preferably less than about 10, alkoxidemoieties.

[0047] Suitable alkyl polysaccharides are decyl, dodecyl, tetradecyl,pentadecyl, hexadecyl, and octadecyl, di-, tri-, tetra-, penta-, andhexaglucosides, galactosides, lactosides, fructosides, fructosyls,lactosyls, glucosyls and/or galactosyls and mixtures thereof.

[0048] The alkyl monosaccharides are relatively less soluble in waterthan the higher alkyl polysaccharides. When used in admixture with alkylpolysaccharides, the alkyl monosaccharides are solubilized to someextent. The use of alkyl monosaccharides in admixture with alkylpolysaccharides is a preferred mode of carrying out the invention.Suitable mixtures include coconut alkyl, di-, tri-, tetra-, andpentaglucosides and tallow alkyl tetra-, penta-, and hexaglucosides.

[0049] The preferred alkyl polysaccharides are alkyl polyglucosideshaving the formula

R₂O(C_(n)H_(2n)O)r(Z)_(x)

[0050] wherein Z is derived from glucose, R is a hydrophobic groupselected from the group consisting of alkyl, alkylphenyl,hydroxyalkylphenyl, and mixtures thereof in which said alkyl groupscontain from about 10 to about 18, preferably from about 12 to about 14carbon atoms; n is 2 or 3 preferably 2, r is from 0 to 10, preferable 0;and x is from 1.5 to 8, preferably from 1.5 to 4, most preferably from1.6 to 2.7. To prepare these compounds a long chain alcohol (R₂OH) canbe reacted with glucose, in the presence of an acid catalyst to form thedesired glucoside. Alternatively the alkyl polyglucosides can beprepared by a two step procedure in which a short chain alcohol (R₁OH)can be reacted with glucose, in the presence of an acid catalyst to formthe desired glucoside. Alternatively the alkyl polyglucosides can beprepared by a two step procedure in which a short chain alcohol (C₁₋₆)is reacted with glucose or a polyglucoside (x=2 to 4) to yield a shortchain alkyl glucoside (x=1 to 4) which can in turn be reacted with alonger chain alcohol (R₂OH) to displace the short chain alcohol andobtain the desired alkyl polyglucoside. If this two step procedure isused, the short chain alkylglucosde content of the final alkylpolyglucoside material should be less than 50%, preferably less than10%, more preferably less than about 5%, most preferably 0% of the alkylpolyglucoside.

[0051] The amount of unreacted alcohol (the free fatty alcohol content)in the desired alkyl polysaccharide surfactant is preferably less thanabout 2%, more preferably less than about 0.5% by weight of the total ofthe alkyl polysaccharide. For some uses it is desirable to have thealkyl monosaccharide content less than about 10%.

[0052] The used herein, “alkyl polysaccharide surfactant” is intended torepresent both the preferred glucose and galactose derived surfactantsand the less preferred alkyl polysaccharide surfactants. Throughout thisspecification, “alkyl polyglucoside” is used to include alkylpolyglycosides because the stereochemistry of the saccharide moiety ischanged during the preparation reaction.

[0053] An especially preferred APG glycoside surfactant is APG 625glycoside manufactured by the Henkel Corporation of Ambler, PA. APG25 isa nonionic alkyl polyglycoside characterized by the formula:

C_(n)H_(2n)+1O(C₆H₁₀O₅)_(x)H

[0054] wherein n=10 (2%); n=122 (65%); n=14 (21-28%); n=16 (4-8%) andn=18 (0.5%) and x (degree of polymerization)=1.6. APG 625 has: a pH of 6to 10 (10% of APG 625 in distilled water); a specific gravity at 25° C.of 1.1 g/ml; a density at 25° C. of 9.1 lbs/gallon; a calculated HLB of12.1 and a Brookfield viscosity at 35C, 21 spindle, 5-10 RPM of 3,000 to7,000 cps.

[0055] The anionic and alkyl polyglucoside surfactants discussed aboveare solubilized in an aqueous medium comprising water and optionally,solubilizing ingredients such as C₁-C₄ alkanols and dihydroxy alkanolssuch as ethanol isopropanol and propylene glycol. Suitable water solublehydrotropic salts include sodium, potassium, ammonium and mono-, di- andtriethanolammonium salts of xylene and cumene sulfonates. While theaqueous medium is primarily water, preferably said solubilizing agentsare included in order to control the viscosity of the liquid compositionand to control low temperature cloud clear properties. Usually, it isdesirable to maintain clarity to a temperature in the range of 5° C. to10° C. Therefore, the proportion of solubilizer generally will be fromabout 1% to 15%, preferably 2% to 12%, most preferably 3% to 8%, byweight of the detergent composition with the proportion of ethanol, whenpresent, being 5% of weight or less in order to provide a compositionhaving a flash point above about 46° C. Preferably the solubilizingingredient will be a mixture of ethanol and either sodium xylenesulfonate or sodium cumene sulfonate or a mixture of said sulfonates orethanol and urea. Inorganic salts such as sodium sulfate, magnesiumsulfate, sodium chloride and sodium citrate can be added atconcentrations of 0.5 to 4.0 wt. % to modify the cloud point of thenonionic surfactant and thereby control the haze of the resultantsolution. Various other ingredients such as urea at a concentration ofabout 0.5 to 4.0 wt. % or urea at the same concentration in combinationwith ethanol at a concentration of about 0.5 to 4.0 wt. % can be used assolubilizing agents. Other ingredients which have been added to thecompositions at concnetrations of about 0.1 to 4.0 wt. percent areperfumes, sodium bisulfite, ETDA, isoethanoeic and proteins such aslexine protein.

[0056] Polyethylene glycol maybe is used in the instant composition hasa molecular weight of 200 to 1,000 wherein the polyethylene glycol hasthe structure

HO(CH₂CH₂O)_(n)H

[0057] wherein n is 4 to 52. The concentration of the polyethyleneglycol in the instant composition is 0 to 7 wt. %, more preferably 0.1wt. % to 5 wt. %.

[0058] The proton donating agent is selected from the group consistingof inorganic acids such as sulfuric acid and hydrochloric acid andhydroxy containing organic acid, preferably a hydroxy aliphatic acid,which are selected from the group consisting of lactic acid or citricacid, orthohydroxy benzoic acid or citric acid or glycolic and mixturesthereof.

[0059] The water is present in the composition at a concentration ofabout 5 wt. % to 70 wt. %.

[0060] The cleaning composition of this invention may, if desired, alsocontain other components either to provide additional effect or to makethe product more attractive to the consumer. The following are mentionedby way of example: Antibacterial agents such as2,4,4′-trichloro-2′hydroxydiphenyl ether colors or dyes in amounts up to0.5% by weight; preservatives or antioxidizing agents, such as formalin,5-bromo-5-nitro-dioxan-1,3; 5-chloro-2-methyl-4-isothaliazolin-3-one,2,6-di-tert.butyl-p-cresol, etc., in amounts up to 2% by weight; and pHadjusting agents, such as sulfuric acid or sodium hydroxide, as needed.

[0061] The product of the present invention comprises a water insoluablesubstrate with one or more layers. Each layer may have differenttextures and abrasiveness. Differing textures can result from the use ofdifferent combinations of materials or from the use of differentmanufacturing processes or a combination thereof. A dual texturesubstrate can be made to provide the advantage of a more abrasive sidefor cleaning difficult to remove soils. A softer side can be used forfine dishware and flatware. The substrate should not dissolve or breakapart in water. It is the vehicle for delivering the cleaningcomposition to dishware, flatware, pots and pans. Use of the substrateenhances lathering, cleaning and grease removal.

[0062] A wide variety of materials can be used as the substrate. Itshould have sufficient wet strength, abrasivity, loft and porosity.Examples include, non woven substrates, wovens substrates,hydroentangled substrates and sponges.

[0063] Examples of suitable non woven water insoluable substratesinclude, 100% cellulose Wadding Grade 1804 from Little RapidsCorporation, 100% polypropylene needlepunch material NB 701-2.8—W/R fromAmerican Non-wovens Corporation, a blend of cellulosic and syntheticfibres-Hydraspun 8579 from Ahlstrom Fibre Composites, and 70%Viscose/30% PES Code 9881 from PGI Nonwovens Polymer Corp.

[0064] Another composite material manufactured by Texcel from a layer ofcoarse fiber 100% polypropylene needlepunch, an absorbent cellulose coreand a fine fiber polyester layer needlepunched together. Thepolypropylene layer can range from 1.5 to 3.5 ox/sq. yd. The cellulosecore is a creped paper layer ranging from 0.5 to 2 ox/sq. yd. The finefiber polyester layer can range from 0.5 to 2 oz/sq. yd.

[0065] Still another composite material manufactured by Texcel from alayer of coarse fiber 100% polypropylene needlepunch, an absorbentcellulose core and a fine fiber polyester layer needlepunched together.The polypropylene layer can range from 1.5 to 3.5 oz/sq. yd. Thecellulose core is a creped paper layer ranging from 0.5 to 2 oz/sq. yd.The fine fiber polyester layer can range from 0.5 to 2 oz/sq. yd. Thepolypropylene layer is flame treated to further increase the level ofabrasivity. The temperature of the flame and the length of time thematerial is exposed can be varied to create different levels of surfaceroughness.

[0066] The abrasiveness is tested by cutting one quarter inch thickLucite boards to fit an abrader bed. The boards are marked to indicatethe track of the wipes during abrasion (approximately 2¼ and 4½ inchesfrom one long edge) and three spots along the track (6, 9 and 12 inchesfrom the short end). This gives unique and reproducible locations atwhich to do gloss measurements which are in the center of the abrasiontrack.

[0067] Using a BYK-Gardener Haze-Gloss glossmeter, the indicated spotsare measured for starting gloss. An average and standard deviation isreported for each track using the three measurements.

[0068] Pieces of the wipes are cut approximately 3 inches by 2 inches.This piece is wrapped around a piece of sponge that fits in a holder forthe abrader. (Indication should be made of whether the material is beingused in the machine or cross direction). This wrapped sponge is placedin the holder, tucking all the edges of the wipe into the holder so thatit is kept firmly in place. The dry sponge is wetted with approximately20-25 g of water (either deionized, distilled or tap as the experimentdesires). This is done so that there are two wipes in the trial.

[0069] The gloss measured Lucite board is placed in the abrader bed. Setthe abrader for 500 cycles and start.

[0070] After the abrader cycles have ended, the Lucite board is removed.It is wiped dry with paper towel to remove any residual water. It isalso inspected for any fingerprints incurred during handling and theseare also wiped clean. Remeasure the gloss at the specified spots againand again report the average of these three spots and the standarddeviation for each track.

[0071] The higher the abrasiveness of the wipe, the more that itroughens the surface of the Lucite and the more the gloss is reduced.The most abrasive of the wipes therefore give the greatest decrease ingloss. Results for this test are given below.
